ROOF BRACKET OR JACK.

To'allwhomt'tmdy. concern: a I 1 Be it known that l, OsoAR SoHoRN, a citizen of-theUnited-States, residing at Cleveland, county of Guyahoga, and State of Ohio, have invented a certain new and useful Improvement in Roof Brackets or Jacks, of which the following is aspecification.

My invention relatesto improvements in roof brackets or jacks. The object of my invention isfor the purpose of providing an adjustable support for planks, scaffolding, material or workmen while being on roofs.

A further object of my invention is to provide a deviceof the (character mentioned, which may. be readily and easily attached and detached on any slate or shingle roof without the necessity of using additional fastening. I

With these objects in view, my invention will be more readily understood by reference to the accompanyingv drawings forming a part of this specification, and in which, 1

Figure 1 is a sideelevation of the preferred form of my'device, Fig. 2 is-a front elevation thereof, Fig. 3 is a top plan, and Fig. 42 shows thewpreferred method of attaching same to roof. 1

Referring now to the drawings; 1 indicates a steel blade of a suitable length, width and thickness with suitable hooks provided at 22. Said hooked blade is for the purpose of inserting. under slates or shingles and engaging at said hooks 22 with nail, with which said slates or shingles are fastened. 3 indicates a suitable base of metal securely fastened to said hooked blade 1 preferably as shown in drawing. Said base is for the purpose of laying on roof and forming a support for adjustable arms of bracket and means for fastening same. This bracket consists of two adjustable arms marked 4 and 5 in drawing which may be of metal or wood. The upper or carrying arm 4: which in drawing consists of two suitable pieces of metal, riveted together, is

fastened to base 3 by means of pivotal bolt 6 and metal lugs 8 and 9 as shown in draw ings. The free end of upper arm is spread and bent in a manner as to form a slot 10 of suitable size to receive free end of lower or supporting arm 5. The lower or supporting arm consists of a suitable piece of metal, and is fastenedtobase with pivotal bolt 7 This lower or supporting arm 5 has a suitable Specification of Letters Patent.

along hooked blade 1. a j j Base 3 is bent upwardly at the lower-end; toa suitable angle, then doubled back over pivotal bolt 7 that which holds supporting number of holes or notches cut preferablyas:l

shown in Fig. 1. "Notches 1212-.12 are for the purpose of engaging bolt or rivet 11 in upper arm 4: and holding said arm 4 at any angle required by pitch of roof. The same may be also accomplished by inserting a boltor pin in holes, if such are used in i I place of notches. The supporting arm 5 be-' ing' sufliciently long above the notches to extend over carrying arm 4, prevents the plank from sliding off of the bracket. Said arms are designed to be disengaged at the free ends, and to fold compactly: supportcarrying arm 4 ing arm 5 along base 3 and arm 5.; This forms a strongsocket into which the elongated toothed blade 13 is fitted. Said blade 13 is securely fastened at 5 1 right angles to base .3 by means of a bolt in drawing. Said blade 13 being fastened with winged nut 14 substantially as shown in this manner to base 3 with severaljinches of blade on either side of said base, pre- 1 vents all lateral movement, orside strain ,of

the bracket when, in use. Said toothed blade 13 is also for the purpose ofgripping roof when the'bracket is hooked on-shingle roofs.

l/Vhen hooked on slate roofs said toothed bladeinay be used for cutting a smallgroove into slates, into which said blade will fit, thereby giving additional security.

Fig. 4 shows a section of roof and the preferred manner of attaching bracket to same. It also shows arms of bracket adjusted to a horizontal position for the purpose of supporting planks, scaffolding, material or workmen which may be placed upon same.

In operation the bracket is secured to roofs in the following manner: By inserting the hooked blade 1 under the slates or shingles as far as desirable, then moving same to right or left until nail holding said slates or shingles is located: Then by drawing the edge of said hooked blade along nail said hooked blade can be easily hooked to said nail at 2. The said nail can be tested by giving a strong downward pull on bracket. By working the toothed edge of blade 13 from side to side a groove is quickly cut, into which said blade 13 will fit. Said blade 13 in conjunction with the hooked blade'1,

h oked to nail, will hold bracket'securely on justable roof brackets having nail strips with notches for nailing to roofs, while being laid,

" havebeen made. I therefore do not claim such a combination broadly, but

I claim? l'. A roof bracket or jack comprising a suitable base of heavy band iron or steel having its lower end doubled back over a pivotal bolt "the double part being bent upwardly to an acute angle to said base, a steel blade inserted between said double part and clamped securely to said base by means of a bolt with winged nut passing through holes provided in said double part and centerof steel blade, suitable teeth cut into lower edge of said steel blade for the purpose of gripping r'oof and for cutting a small groove in slate or shingles, into which said steel blade will fit and prevent said base from sliding downward, said steel blade to be of sufiicient size to extend several inches on each side of base and thereby prevent all lateral movement 'and side play of said base substantially asdescribed.

2. A roof-bracket or jack comprising a base of heavy band iron or steel having its lower end doubled back and bent upwardly to an acute angle to said base, a transverse slot cut through the eye formed by said two subscribing witnesses.

double pm, a steel arm hinged intothe said slot by means of a pivotal bolt passing through eye of double part and a hole in lower end ofsteel arm, a series of upwardly opening notches cut into outside edge ofsa'id st-eel arm, another arm hinged at the upper end of saidbase and consisting of two metal strips riveted together for about two-thirds of their length, and then spread apart to form a U shaped slot theopen end of which is closed by a bolt or rivet, said slot being of sufficient widthto admit free end of lower arm and thereby forming a bracket'of great strength which :can be quickly adjusted to pitch of roof'by means of the'notches cut into lower arm and engagingthe bolt or rivet closing free end of upper arm, substantially as described. l a p 3. In a roof bracket or jack the combination of a suitable base of heavy band iron or steel having its lower end doubled back over "a pivotal bolt the said doublepart being bent upwardly to an aeute'angle to the base,

thereby providing a convenient socket into which a toothed saw blade can be clamped 'as described, and also forming a suitable support to which the lower arm of adjust able bracket can described. In testimony be hinged substantially as whereof Ihave signed iny name to this specification in the presence of OSCAR scrionn;
